Different aspects of the integration of conventional control system and knowledge-based systems are discussed. Special requirements such as multiple forms of knowledge representation, support for model-based reasoning, and real-time operation are discussed. Three different forms of integration are described: interfaced systems, embedded systems, and totally integrated systems.
The transport sector accounts for approximately 20% of EU-27 greenhouse gas (GHG) emissions, and 27% of U.S. GHG emissions. With the Kyoto Protocol, Sweden and several other nations have agreed to reduce these emissions. Often, solutions that involve consolidating freight and moving it to more carbon-efficient transport technologies are advocated as the most advantageous. For such initiatives the
A fedbatch process shows exponential growth under ideal conditions. To obtain good substrate concentration control it is necessary that the regulator can track an exponentially growing feed demand, and standard PI-control has to be supplemented with an estimated basic dosage to get reasonable control. However, an exponentially growing concentration error is impossible to avoid. An I-term could be
This is a study of farm dynamics in eight African countries, drawing on a sample of more than 3000 farm households. It deals mainly with food crops and in detail with maize and makes a longitudinal analysis by systematically comparing current conditions with those obtaining when the farm was set up under its present management. From the study emerges an overall picture of inadequately exploited pr

This chapter explores the fertility behavior, specifically the transition to parenthood, of the second generation, i.e. the children of immigrants, in Sweden from an integration perspective. We examine the impact of education, income, labor market attachment, nationality and immigrant experience on first births of second generation women and contrast it with that of the native Swedish-born populat
